The apartment was true to what you see in the photos. It was a private, beautiful, spacious and comfortable house with good amenities. It is fantastic for a group of friends/family visiting Bangkok and would like to stay together.
I did not get to meet Top throughout the stay, but liaised with Sebastian - a staff at CondoBNB that manages about 20 odd/30 apartments in Bangkok and rents them out for short stays on Airbnb. With that, you cannot expect the host/ Sebastien to provide detailed information regarding the apartment or what's around. However, what makes up for this is the presence of a staff at the apartment in the day to help you with your queries. This was greatly appreciated.
What could possibly be a downside is the location off Sathorn Soi 1 in a residential area with nothing much around it. It is difficult to hail a cab (we booked uber/grab everyday when we went out) and may be inaccessible to first time visitors. However, this will not be an issue if you are familiar with Bangkok.
